specific Embodiment 2

[0047] The specific embodiment 2 of the quick-release threaded fastener of the present invention is different from the specific embodiment 1 in that, in order to ensure that the entire quick nut has a higher locking strength, the inner concave arc of the U-shaped block part of the nut seat is The inner wall of the light can also be replaced with the inner wall of the inner concave arc thread that matches with the inner wall of the inner concave arc thread of the movable seat. The complete full-threaded combination hole of the helix, and the full-threaded combination hole and the guide light hole are in the coaxial position, and the nut seat and the movable seat are respectively engaged with the threaded section of the bolt from the left and right directions to ensure that the entire quick nut can be used for the workpiece. Apply more tightening force.

specific Embodiment 3

[0048] The specific embodiment 3 of the quick-disconnect threaded fastener of the present invention is different from the specific embodiment 1 in that the movable seat can be set as the lowest part of the movable seat under the premise of low requirements on the shape regularity of the quick-release nut. The lower end protrudes downward from the lower end surface of the nut seat. When the workpiece is fastened with the quick-release nut, only the lower end of the movable seat is used to tighten the workpiece, while the lower end surface of the nut seat is in a suspended state.

specific Embodiment 4

[0049] The specific embodiment 4 of the quick-release threaded fastener of the present invention is different from the specific embodiment 1 in that the rectangular block part integrally provided on the nut seat can be omitted, which is equivalent to reducing the guide light hole located at the upper part, Correspondingly, when the quick-release nut is used for direct movement in the axial direction of the bolt, the inner wall of the concave arc thread of the movable seat may be connected to the thread segment of the bolt due to the lack of the guiding function of the light hole of the rectangular block part. A jam occurs between them.

[0050] The specific embodiments of the quick disassembly and assembly nut of the present invention are the same as the specific embodiments of the quick disassembly and assembly threads in the specific embodiments of the quick disassembly and assembly threaded fastener of the present invention, and are not repeated here.

Abstract

The invention provides a threaded fastener capable of being quickly dismounted and a nut thereof. The threaded fastener capable of being quickly dismounted comprises a bolt and a quick dismounting nut, wherein a blocking part of a radial blocking bolt is arranged on a nut base; the blocking part is provided with a main axis which is superposed with the axis of the bolt; a matched threaded part which is in threaded fit to a threaded section of the bolt is arranged on a movable base; the rotation axis of the movable base is perpendicular to the extending direction of the main axis; the uppermostend of the matched threaded part of the movable base is not higher than the rotation axis; the movable base rotates relative to the nut base, and is provided with a locking position which is in buttjoint with the blocking part of the nut base to form an assembly hole of a radial constraint bolt, or an unlocking state which is separated from the blocking part of the nut base for relieving radialconstraint on the bolt; and when the movable base is on a locking position, the axis of the assembly hole is superposed with the main axis, the matched threaded part of the movable base is engaged with the threaded section of the corresponding bolt, and the lowest end of the movable base is provided with a jacking surface which jacks a workpiece to prevent the movable base from unlocking.

Description

technical field [0001] The invention relates to the technical field of threaded fasteners, in particular to a quick disassembly threaded fastener and a nut thereof. Background technique [0002] Bolts and nuts are common threaded fasteners in engineering practice. If the threaded section of the bolt is long during the disassembly and assembly of the nut, it takes a long time to twist the nut to remove it. In the occasions where bolts and nuts often need to be disassembled , The disassembly and assembly operation of the nut is inconvenient, and the external thread of the bolt and the internal thread of the nut are also easily worn, which shortens the service life of the bolt and the nut. [0003] For example, the Chinese utility model patent with the authorized announcement number CN203702814U and the authorized announcement date of 2014.07.09 discloses a lock nut. The lock nut includes a left nut and a right nut that cooperate with each other. The left and right nuts are res...
